Revision: 636 http://treebase.svn.sourceforge.net/treebase/?rev=636&view=rev Author: hlapp Date: 2010-03-20 18:16:27 +0000 (Sat, 20 Mar 2010) Log Message: ----------- Looks like this has been deprecated and is now in WEB-INF/pages. Removed Paths: ------------- trunk/treebase-web/src/main/webapp/help/urlAPI.jsp Deleted: trunk/treebase-web/src/main/webapp/help/urlAPI.jsp =================================================================== --- trunk/treebase-web/src/main/webapp/help/urlAPI.jsp 2010-03-20 18:12:59 UTC (rev 635) +++ trunk/treebase-web/src/main/webapp/help/urlAPI.jsp 2010-03-20 18:16:27 UTC (rev 636) @@ -1,110 +0,0 @@ -<%@ include file="/common/taglibs.jsp"%> - -<title>URL API</title> -<content tag="heading">URL API</content> -<body id="submissions"/> -<p> - The TreeBASE2 website provides users with simple ways to navigate the underlying data - programmatically. This page describes the stateless web service interface and URL architecture - that can be used to search the web site and obtain data in a variety of formats with rich semantics. -</p> -<h3>PhyloWS support</h3> -<p> - The site structure described here is designed to be compliant with the emerging - <a href="http://evoinfo.nescent.org/PhyloWS">PhyloWS</a> standard. One of the tenets of the - standard is that URLs contain a <strong>/phylows/</strong> delimiter below which the standard - recommends a <a href="https://www.nescent.org/wg_evoinfo/PhyloWS/REST">simple API</a> to derefence - phylogenetic data by their accession numbers. In the examples below, the url fragments come - immediately below the <strong>/phylows/</strong> delimiter (everything between the - <strong>http://</strong> and <strong>phylows</strong> is considered - subject to change, likely to be stabilized using <a href="http://purl.org">purl</a> addresses). -</p> -<h3>Site sections</h3> -<p>The data on the TreeBASE2 website are organized in four subsections:</p> -<ul> - <li><strong>taxon/</strong> <em>operational taxonomic units, taxonomic mappings and outlinks</em></li> - <li><strong>matrix/</strong> <em>character state matrices, morphological character definitions</em></li> - <li><strong>tree/</strong> <em>contains trees and tree nodes</em></li> - <li><strong>study/</strong> <em>full submission records, including citation and analysis records</em></li> -</ul> -<p> - Within those four sections, every item in the TreeBASE2 database can be de-referenced by appending - the item's full identifier to the right section name. For example, <strong>tree/TB2:Tr2227</strong> - represents a tree (and returns a simple RDF file to describe the tree). For some classes of objects, - these short addresses can be passed a <strong>format</strong> - parameter to specify in which data format to represent the object: - <a href="/treebase-web/phylows/study/TB2:S1787?format=html">study/TB2:S1787?format=html</a>. - Identifiers that match any of the following expressions can be represented as <strong>nexml</strong>, - <strong>nexus</strong>, <strong>rdf</strong> or <strong>html</strong> (i.e. in a web page): -</p> -<ul> - <li><strong>matrix/TB2:M[0-9]+</strong> <em>character state matrix</em></li> - <li><strong>tree/TB2:Tr[0-9]+</strong> <em>phylogenetic tree</em></li> - <li><strong>study/TB2:S[0-9]+</strong> <em>study record</em></li> -</ul> -<h3>NeXML support</h3> -<p> - The <strong>nexml</strong> and the <strong>rdf</strong> download options both use output - generated by the java support libraries available from the - <a href="http://nexml.org/nexml/java">nexml website</a>. The website uses the nexml annotation - feature extensively to transmit all the metadata stored by the database. Nexml annotations - are <a href="http://www.w3.org/TR/xhtml-rdfa-primer/">RDFa</a> compliant element structures - that use <a href="http://www.w3.org/TR/curie/">CURIE</a> strings to identify metadata properties, - and @content attributes to store the property value. For example, this (simplified) annotation: - <strong> - <meta content="uBio:2538170" property="tb:identifier.ubio"/> - </strong> - means that the element that encloses it has a special kind of identifier attached to it, namely - one that TreeBASE recognizes as originating in <a href="/treebase-web/phylows/taxon/uBio:2538170">uBio</a>. -</p> -<p> - The salient part is - the CURIE string predicate <strong>tb:identifier.ubio</strong>, which is one of a - <a href="http://spreadsheets.google.com/pub?key=rL--O7pyhR8FcnnG5-ofAlw">long list</a> of - proposed predicates that are written in TreeBASE's NeXML output and can be used as - <a href="http://www.loc.gov/standards/sru/specs/cql.html">CQL</a> search predicates. The predicates - proposed (and now experimentally transmitted) are intended to be subclasses of predicates - from commonly used vocabularies. For example, <strong>tb:identifier.ubio</strong> inherits from - <a href="http://dublincore.org/documents/dcmi-terms/#terms-identifier">dcterms:identifier</a> and - so any of the latter's semantics apply to the former, which is refined to indicate that the - value is a uBio namebank ID. -</p> -<h3>Searching</h3> -<p> - The TreeBASE website can be searched using a subset of constructs from the - <a href="http://www.loc.gov/standards/sru/specs/cql.html">CQL</a> specification. Specifically, - the predicates - <a href="http://spreadsheets.google.com/pub?key=rL--O7pyhR8FcnnG5-ofAlw">listed here with - an asterisk</a> can be used in statements in the site section they apply to, such that, for example - a taxon can be retrieved by its ncbi ID like so: - <div style="background-color:;padding:10px"> - <strong>taxon/find?query=tb.identifier.ncbi=<em><ncbi taxon id></em></strong> - </div> - or by its name like so: - <div style="background-color:;padding:10px"> - <strong>taxon/find?query=tb.title.taxon=<em><name></em></strong> - </div> - or using an exact match - (<strong>==</strong>) or a case-insensitive one (<strong>=/ignoreCase</strong>). These statements - can be combined with boolean <strong>and</strong>, <strong>or</strong> and <strong>not</strong>. - For example: - <div style="background-color:;padding:10px"> - <strong>study/find?query=dcterms.contributor=Huelsenbeck or dcterms.contributor=Ronquist</strong> - </div> - Finally, searching can be modified to project the results from one section info those of another. The - effect is roughly the same as switching between tabs in the search section: if the results are a - list of tree and you click on the matrix search tab, the trees are converted to the set of matrices - on which the trees are based. This behaviour can be used by specifying the - <strong>recordSchema=<section></strong> argument, i.e.: - <div style="background-color:;padding:10px"> - <strong>taxon/find?query=dcterms.title=="Homo sapiens"&recordSchema=tree</strong> - </div> - returns all the trees that have <em>Homo sapiens</em> in them. - By default, all these queries return a web page, but with a <strong>format=rss1</strong> argument - the search results are listed in an RDF compatible RSS1.0 file, i.e.: - <div style="background-color:;padding:10px"> - <strong>taxon/find?query=tb.title.taxon=<em><name></em>&format=rss1</strong> - </div> - The returned results in RSS1.0 use the short urls of the form <strong><section>/<id></strong>, whose - returned resource descriptions (like <a href="/treebase-web/phylows/tree/TB2:Tr2227"> - this</a> one) need to be scanned to discover suitable serialization formats. \ No newline at end of file This was sent by the SourceForge.net collaborative development platform, the world's largest Open Source development site. |
